So try to kill the process 1440

Code: Select all

kill -9 1440

then repeat the ps command to check if mount command is really aborted and then the first telnet window should no longer be hanged

[pasqualeCatucci]

nothing|:-( it doesn't stop. I tried many times but the process remain alive. I see that doesn't exist "sudo" command.

[Jocko]

You can try with another kill signal

Code: Select all

kill -15 1440

If no change, then you need to stop the nas (you can try the command halt but not sure that works) and restart the fvdw-sl console.
So after getting the new telnet window, you have to repeat some actions: load the tools package, re-assemble the raid md4 and then do the actions how to repair the fs

[pasqualeCatucci]

So the first step is formatting the usb stick :
- plug it
and run

Code: Select all

udevstart

and look at its partition table

Code: Select all

fdisk -l /dev/sdc

(should get as kernel device name: sdc. If it fails to find sdc, please to post the output

Code: Select all

cat /proc/partitions

, and do not continue further )
- create a new table

Code: Select all

fdisk /dev/sdc
                                  Then do(delete the current partition, I assume there is only one)
d
1
                                  (create a new one)
n
p
1
1
1000

t
1 ((this make the type of filesystem at FAT12. I think that it is a misprint or you want to write L for list))
82
w

next is to create the swap system on sdc1

Code: Select all

mkswap /dev/sdc1

((after this command I have this message))

Code: Select all

root@fvdw-sta-kirkwood:/ # mkswap /dev/sdc1
mkswap: lseek: Value too large for defined data type


This is the output of fdisk -l

Code: Select all

root@fvdw-sta-kirkwood:/ # fdisk -l /dev/sdc

Disk /dev/sdc: 4018 MB, 4018192384 bytes
124 heads, 62 sectors/track, 1020 cylinders
Units = cylinders of 7688 * 512 = 3936256 bytes

   Device Boot      Start         End      Blocks  Id System
/dev/sdc1               1        1000     3843969  82 Linux swap


and bring up the new swap partition

Code: Select all

swapon /dev/sdc1

Check if you get a not empty swap size with the command

Code: Select all

free

If yes, you can now try again to run the xfs_repair command

Code: Select all

tftp -l /sbin/xfs_repair -r xfs_repair -g IP-PC
chmod a+x /sbin/xfs_repair

(IP-PC is the IP address of your laptop like 192.168.1.xx)
and run it

Code: Select all

xfs_repair /dev/md4

If you want to make a check without fixing (just list what actions are required), you can add the option '-n' in this command

[pasqualeCatucci]

I resolved and this is the result of repair

Code: Select all

root@fvdw-sta-kirkwood:/ # xfs_repair /dev/md4
Phase 1 - find and verify superblock...
Phase 2 - using internal log
        - zero log...
ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed.  Mount the filesystem to replay the log, and unmount it before
re-running xfs_repair.  If you are unable to mount the filesystem, then use
the -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this.


[pasqualeCatucci]

I'm trying with -L option ... finger crossed

[pasqualeCatucci]

GREAT! I see the fs!
I mounted /md4 on /dev/md4 and I see the content.
But now if I reboot the NAS I'll see the shares OpenShare and MyShare or should I do something else?

thanks for you help. you are a great guy.

[pasqualeCatucci]

after copying all my data to another storage I would like to install your firmware on the NAS, with your help, if you want :-)

[Jocko]

:-D Nice to heard the fs is now clean.
Did you reboot the nas ? Now you should see your share :?:

You can explore a fake of fvdw-sl web-interface if you want before installing our firmware.

With fvdw-sl console you can install it without manual action
